Final answer:
The graph of frequency vs place of maximum vibration in the cochlea indicates how different regions of the basilar membrane are sensitive to sounds of different frequencies and how the cochlea separates auditory stimuli by frequency.
Step-by-step explanation:
Pressure waves moving through the cochlea cause the basilar membrane to vibrate at different positions for different frequencies. This vibration pattern is represented by the graph of frequency vs place of maximum vibration in the cochlea. The graph indicates that different regions of the basilar membrane are sensitive to sounds of different frequencies, with high frequencies stimulating nerves at the near end and low frequencies stimulating nerves at the far end. The graph provides a visual representation of how the cochlea separates auditory stimuli by frequency, allowing us to perceive different pitches.
